Fig. 5 is a detail side thus far described constitute parts of the No. view of one of the top carrying disks; and 6 Remington machine and a further descrip- Fig. 6 is a detail side view showing the other tion thereof is deemed unnecessary.

My billing attachment comprises a ratchet wheel 24 rigidly seeured to. the platen shaft near the right handend thereof by a set screw 25. A disk 26 has a central bearing opening through which the platen shaft projects so that the disk is loosely mounted on the shaft and is adapted to bear at one side thereof against the inner side of the ratchet wheel 24, as shown Fig. 3. A pawl 27 is pivoted at 28 to the disk or plate'26 and is provided with two flat faces 29 and 30 with which a spring 81 cooperates. This spring is. formed with a convolute, near one. end. through which the stem of a headed screw 32 projects, the screw taking into a threaded. opening in the disk and the adjacent end of the spring beingbent and seated in an opening 33 in the disk. A small finger piece 34 is provided on the pawl so that it may be moved. by hand to either the full or dotted line osition shown in Fig. 6. When the pawl is in the full line position the spring 3 1 cooperates. with the flat face 29 on the pawl and terrds to maintain the pawl in said full line position and out of engagement with the cooperating ratchet wheel 24. When, however, the'pawl is moved to the dotted line position the spring 31 cooperates with the flat face 30 of the pawl and exerts a pressure thereon to force the nose of the pawl into engagement with the teeth of the ratchet wheel 24. This construction constitutes pawl and ratchet connection between the laten shaft and the disk 26 and indirectly hetween the platen the disk. The disposition of the. teeth on the ratchet wheelis such that when the pawl; is in engagement therewith the disk 26 will be positively connected to be turned with the platen in the backward rotation thereof, though when the disk is arrested as will hereinafter appear, the laten may be turned forwardly, or in the direction of its line spacing movements, to any desired extent independently of the disk 26, The disk 26 has an integral stop 35 which projects outwardly from theperiphery thereof and the stop. has a threaded opening therein for cooperation with a shouldered ivot screw 36 which connects one end of a eaf-spring 37 to, the disk or to the stop carried thereby. The other free end of the leaf spring carries an engaging pin 38 which. has an integral finger-piece 39 by which it may be withdrawn from an opening 40 in the disk 26, and from effective engagement with the contiguous disk 41, as will hereinafter appear. The disk or plate 41 is preferably co.- extensive in diameter with the disk 26 and like the disk 26, has a central opening 42 through which the platen shaft 11 projects-so that the disk 41 is looselymounted on the platen shaft. The disk 41 has a series of engaging openings 43 which are circularly ar..

rangedand are spaced apart to correspond to the spacing between the teeth of the line spacing ratchet wheel 13. This disk 41 is likewise provided with an integral stop 44 which projects outwardly from the periphery thereof. The disks 26 and 41 are arranged side by side and the engaging openings 43 are so arranged that the locking pin 38 when proj ected through the opening 40 in the disk 26 enters one of the o )enings 43 in the disk 41 so as to positively loc r the two disks together in therelation in which they may be adjusted relatively to each other. A coiled expansion spring 45 is interposed between an end or side bar of the platen frame 8 and the disk 4]. so as to press the disk 26 into frictional engagement with the ratchet wheel 24, in order that both disks may be caused to rotate with the platen through frictional engagement of the. disk 26 with the ratchet wheel 24. The stop. pin 21 hereinbeforc referred. to constitutes a part of a headed screw 46, the stenrof which extends through a slot 47 in a bracket arm 48. An outwardly extending arm 49 of this bracket extends across the side bar of the platen frame and into the path of the stops 35 and 44 as they are rotated with the platen, as shown in Fig. The devices of my invention are useful in connection with several kinds of billing work, though they are more especially adapted for condensed record work. a

From the foregoing description it will be understood that the billing devices are located outside of the platen frame where they can be readily applied to the machine without dismounting or disconnecting any parts of the machine except the finger wheel 22 which can be readily removed and replaced.

One mode of o aerating the devices for condensed recor billing work is as fol.- lows: Assuming that the pawl 27 is in engagement with its cooperating ratchet wheel 24, then the platen is turned backwardly until the stop 35 brought into engagement with the cooperating fixed stop 49 and a further backward movement of the platen is prevented. It will be understood that this backward rotation of the stop 35 is effected. by the ratchet wheel 24 which is positively connected to the platen and positively transmits backward. movement to the disk 26 and. its sto 35 through the pawl 27. The con densea record sheet, the invoice sheet and the interposed carbon sheet then introduced into the machine with the leading edges of the sheets brought together into the bight between the main paper feed rollers 50 and the platen. 'l he operator will then turn the platen forwardly in the direction of its line feed movement until the point on the invoice sheet where the first line of writing is to appear is at the printing line. T his may be determined in the first instance by the operator swinging the platen back and observing when the point in question arrives at the printing line. During this feed move:

ment, the disks and stops are carried along with the platen by the frictional contact of the disk 26 and ratchet wheel 24. The looking pin 38 is then withdrawn from its engag ing opening 43 and the disk 41 is turned until the stop 44 thereon is brought into contact with the forward edge of the fixed stop 49 and the two plates are locked together by the in 38, thus efiecting a relative adjustment between the stops 35 and 44 appropriate to the particular hill head employed, and this adjustment is maintained as long that articular kind of bill head is being used.

uring this relative adjustment of the stops 35 and 44, the stop 35 will be maintained by the pawl 27 engaging the ratchet wheel in the position to which it was automatically moved by the forward turning movement of the platen. When the relative adjustment of the stops 35 and 44 has been effected in the manner described the locking pin 38 is seated in the proper engaging opening 43 so as to positively lock the stops in the relation to which they have been adjusted. The stops having been set in the manner described, with the stop 44 in contact with the fixed stop 49,

then the operatormay proceed to write the invoice in the usual manner and the written matter will be reproduced through the carbon on the condensed record sheet During the line feed movement of the platen, pro duced in writing the invoice, the frictional means will maintain the stop 44 in contact with the fixed stop 49. After the invoice has been written the operator should give the laten, say, two line space movements in orel to provide proper space on the condensed record sheet between the last line of the first invoice reproduced thereon and the first line of the next invoice to be written. The platen is then given a rearward rotation until the stop 35 contacts with the fixed stop 49; the platen being positively arrested when the stops are brought into contact. The second invoice sheet is then introduced into the machine with the leading edge thereof in the bight between the feed rollers and platen; the first written invoice remaining in the machine. The platen is then given a forward rotation until the stop 44 is brought into contact with the fixed stop 49, when the first writing line of the new invoice sheet will be in printing position. '1 he operator may then proceed to write the second invoice which will be reproduced through the carbon on the condensed record sheet, with the first line of the second invoice situated two line space distances from the last line of the previously written invoice reproduced on the record sheet. When the second invoice is completed the operator again gives the platen a double line space movement to provide a requisite spacing between invoices on the condensed record sheet and then turns the platen back until it is arrested by the stop 35 coming into contact with the fixed stop 49. T he third invoice sheet may then be introduced as before. The platen is then again given a forward rotation until the stop 44 is brought into contact with the fixed stop 49. 'i he third invoice sheet is then written as before and the operation. is repeated until the record sheet is filled. T he invoice sheets will be automatically fed out of the machine one at a time as subsequent invoice sheets are written or will be fed forwardly to a position where they can be readily removed from the machine without disturbing the other invoice sheets, the carbon sheet, or condensed record sheet.

'i fhen the stops 35 and 44 are once set in the manner described, the machine may be used without further change as long as invoice sheets having the same depth of head ing are employed. After this it is merely necessary to effect a rearward and a forward rotation of the platen and to produce two line space movements thereof for each new invoice sheet introduced into the machine as above described.

.1 hen the machine is to be used' for ordinary work, and not for billing work, the pawl 27 may be moved from the dotted line to the full line position in Fig. 6 wh ere it will be in sintained out of cooperation with the ratchet wheel 24. The stop devices will then be out of operation and the platen can be rotated back *ardly or forwardly to any desired extent without interference by the stops. While it is true tl at this time the stops 35 and 44 will, through their frictional connection with the platen, rotate with it until arrested by the stop 49, after which the platen rotates independently of the stops, nevertheless, the friction exerted by the spring -5 is so slight il at it is not appreciable in the ordinary operation of the machine and does not interfere with such operation in the slightest degree.

The foregoing description applies to one manner of operating the devices for condensed recmrl billing work. It should be understood, however, that various changes in the mode of operating the devices may be mad For in tance, it may be found desir able to give the i3 invoice sheet introduced into the machine with each condensed record sheet and the interposed carbon a lea over the condensed record sheet and carbon, in order that the space at the top of the condensed record sheet may be economize-d. and the first line of writing of the first invoice sheet be made to appear at any desired distance from the top of the condensed record sheet.

From the foregoing description it will be seen that l have provided simple, cheap and efiicient billing mechanism which is in the nature of attachments that may be readily applied to existing forms of typewriting machines without modifying the structural features of said machines; that the devices are. simple in operation and mechanically determine the proper relations between the different invoice sheets and the condensed record sheet as the former are successively introduced into the machine; that no mental calculations are necessary on the part of the operator in either setting or actuating the devices; that there is no burden placed on the mind of the operator in actuating the devices; that the operator has little to remember in. order to accurately operate the devices, the stops 35, 4e: and ll) cooperating to determine the extent of backward. and forward rotation. of the platen necessary to properly position the various invoice sheets with reference to the condensed. record sheet; that the platen is positively arrested in its movement in one direction or in the direction of the backward rotation of the platen when it is turned backwardly to receive a new invoice sheet and properly position the same with reference to the condensed record sheet; that, nevertheless, the platen may receive a forward rotation to any desired extent; that the steps 05 and 4A are positively held in their relative adjustment; and that the frictional means interposed between the stops 35 and 44 and the platen cause the stops to rotate with the platen and afford an independent rotation. of the platen after the stop i l has been brought into contact with the cooperating fixed sto p 49.
